- IIn this paper, we describe a C-band high power amplifier(HPA) Monolithic Microwave Integrated Circuit(MMIC) design and measurement results for satellite transmitters. For a high output power of 20 W, a 0.25 μm GaN process was used and the HPA MMIC with a 2-stage cascade configuration was operated in Class AB mode for high efficiency. The fabricated MMIC has 29 dB gain, 43.3 dBm output power, and 48 % power added efficiency(PAE) with an MMIC size of 3.0 mm×1.8 mm over a frequency range from 5.0 GHz to 7.2 GHz and exhibits an output power density of 3.96 W/mm2.
